Drive Shaft

Our original driveshaft wouldn't work because a 14-bolt uses 1350 U-joints and our 1/2-ton shaft came equipped with wimpy 1310s. The 14-bolt's pinion also is 2 inches farther forward than it is on the 12-bolt. We didn't want to build new driveshafts until our new suspension and drivetrain, all of which we'll tell you about in future issues, were in. Lucky for us, one of the guys at ORU had a driveshaft out of a '72 3/4-ton Suburban lying around in his scrap heap that we could temporarily use. All we had to do was change out the 1310 U-joint yoke on the transfer case for a 1350.
